There is no air brake endorsement. If a CDL driver does not complete and pass the written Air Brakes test and perform their road test in an air brake equipped vehicle, they receive a restriction which prohibits them from operating a commercial vehicle with air brakes.
No, because there is no such thing as an air brake endorsement on a US license.
No, you can get a 3 wheel vehicle endorsement. If you have a motorcycle endorsement, you can drive a trike but not the opposite.
You can't get one, because such an endorsement does not exist.
No such thing as an air brake endorsement on a US license.
Only if it's either designed to transport more than 15 persons (including the driver), or else carrying a quantity of hazardous materials which requires the display of placards under the FMCSR. In both instances, you would need at least a Class C CDL without an air brake restriction (there is no actual air brake endorsement), as well as a passenger endorsement (for a passenger bus) or hazardous materials endorsement.
No. You can't get an air brake endorsement, because it doesn't exist. Non-commercial vehicles equipped with air brakes do not require the operator to have any familiarity with air brake systems (for better for worse). The only time it's applicable is in the case of CDL drivers, who are both required to complete and pass the written air brakes test and perform the road test in an air brake-equipped vehicle, or else they receive a restriction which prohibits them from operating an air brake-equipped commercial vehicle.
Yes, you do. You would need, depending on the vehicle weight, either a Class C CDL (for vehicles under 26,000 lbs) or Class B CDL (for vehicles over 26,000 lbs). If the vehicle was equipped with air brakes, you would have to take the written air brakes test and road test on a vehicle so equipped (there is no actual air brake endorsement - only a restriction), and you would need a "P" endorsement for passengers, or "S" endorsement if you actually were transporting children.
At a minimum, a Class C Commercial Drivers Licence with Passenger endorsement and no air brake restriction (if the vehicle is equipped with air brakes). If the vehicle has a GVWR of over 26,000 lbs (which is a bit unlikely with an 18 passenger vehicle), then a Class B CDL would be required, again with the Passenger endorsement and without a restriction on air brakes, if the vehicle were so equipped.
Depends on where you're at. In the US, there is no such thing as an air brake endorsement - only a restriction for CDL drivers who don't both pass the written air brakes test and perform their road test in a vehicle so equipped. In other countries, there is such an endorsement.
No, you cannot legally drive a manual transmission vehicle in the USA with an automatic license. You need a manual transmission endorsement on your license to do so.
So long as the weight rating of the vehicle doesn't exceed 26k, yes, with two exceptions - you would need a Class C (minimum) CDL with hazmat endorsement if the vehicle is transporting a quantity of hazardous materials which requires placards to be displayed, and you would need a Class C (minimum) CDL with passenger endorsement if it is a bus designed to transport more than 15 passengers (including the driver).
There is no such thing as an air brake endorsement on ANY license in ANY US state or territory. For people with a CDL, if they do not complete and pass the written air brakes test and perform their road test in a vehicle so equipped, they get a RESTRICTION on their CDL which prohibits them from operating a commercial motor vehicle which is equipped with air brakes.
